Casio FX-991MS 2nd Gen Non-Programmable Scientific Calculator, 401 Functions and 2-line Display, Black

Er funktioniert einwandfrei, und wenn jemand das zweizeilige Display im klassischen Stil schätzt ist dieser Rechner eine gute Wahl. Man merkt aber schon anhand des Funktionsumfangs dass er schon in die Jahre gekommen ist und definitiv ein Design der 90er ist. Da ich aber Rechner sammle bin ich froh einen neuen abgestaubt zu haben.

Nice and new

It's very useful for engineering students. Various type of critical problem solved by use of this ,trigonometry function, exponential function etc. It is value for money, accuracy is more, easy to use, battery life is better , better button quality.

Good tools for college student

Solid calculator for students — does the job without drama As an engineering student, the Casio fx-991MS has been a lifesaver for me. It covers all the essential functions — complex numbers, matrices, integration, stats, etc. — without going overboard. The button feedback is decent, the display is clear (dual-line is a plus), and it runs on both solar + battery, so you never get stuck during an exam. It's not flashy like the fx-991EX, but it’s reliable and familiar. And honestly, sometimes that’s all you need. It’s accepted in most Indian exams (JEE, GATE, etc.), which is a big win. Only downside? No high-resolution display and feels a bit "2000s retro" — but that’s part of the charm. TL;DR: Great value, trusted brand, exam-ready — go for it if you don’t need the fancy features of the newer models.
